PERFORATING AND CUTTING DEVICE FOR MULTIGRAPI-IS.

Specification of Letters Patent. Pateutad AIM. 5, 1921 Applicationfiled. March 15, 1920. Serial No. 365,976.

To all whom it may concern:

, Be it known that 1, JOHN WAILES DE MILLY, a citizen ofthe UnitedStates, residing at Tallahassee, in the county of Leon and State ofFlorida, administrator of the estate of lVILLIAM TAYLOR CoLLINs, late acitizen of the United States, and a resident of Tallahassee, Florida. dodeclare that the said lVILL-nmr TAYLOR COLLINS has invented certain newand useful Improvements in Perforating and Cutting Devices forMultigraphs, of which the following is a specification.

This invention relates to a device for cutting and perforating sheets ofpaper which is in the form of an attachment so that it may be applied toamultigraph machine of the ordinary construction for perforating.

and cutting the paper as it leaves the machine.

It is a purpose of this invention to provide an attachment of the abovedescribed character in which the cutting and perforating blades areassociated with supporting disks to permit of the removal andsubstitution of other disks when they become worn or broken. 7

It is also a purpose of this invention to provide a roller which coactswith the blades in effecting the perforating and cutting of the sheetsof paper, such roller comprising two sections which are held in spacedrelation to provide a slot for the reception of the cutting edge of theblades, and are adjustable with respect to each other to provide agroove of a predetermined width to accommodate a particular blade.

I will describe one form of device embodying this invention and twoforms of blades, and will then point out the novel features thereof inclaim.

In the accompanying drawings:

Figure 1 is a view showing in side elevation a conventional form ofpaper feeding means for a multigraph machine having applied thereto oneform of perforating and cutting device embodying this invention.

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a View similar to Fig. 2 showing a cutting blade substitutedfor the perforating blade shown in Fig. 2.

. Fig. 1 is an enlarged detail'view of the perforating blade. I

Figs. 5 and 6 are detail views of the sections comprised in the bladecarrying roller. F igs. 7, 8, 9 and 10 are detail views of the coactingfeeding rollers. Similar reference characters refer to similar partsineach of the several views.

Referring specifically to the drawings and particularly to Fig. 1, Fdesignates a frame 1n which is journaled a pair of superposed shafts, Sand S carrying coacting feed roll rs R for effecting the feeding ofsheets of paper from a multigraph machine.

The device embodying the subject matter of this invention comprises,alarge feed roller designated generally at A and includmg a section 15having a collar 16, and a section 17 which is adapted'to be clamped withthe section 15 for supporting a perforating blade I: or a cutting bladeB therebetween. As illustrated to advantage inFigs. 5 and-6, thesections 15 and 17 are of disk formation and. are formed with axialopenings through which the] shaft. S is adapted to extend.

They are also provided with other openings through which screws 18extend forclampmg the two sections together. The collar 16 of thesection 15 carries a set screw 19 which 1s adapted to engage the shaft Sfor locking the roller as a unit upon the shaft.

- As shown in Fig.4, the perforating blade B is of disk formationv withthe marginal edge thereof serrated to provide teeth 20. This blade isalso formed with openings for the reception of the screws 18 and theshaft S.

As shown in Fig. 1, the roller A coactn with a relatively small roller Awhich consists of two sections21 and 22 connected to each other byscrews 23 and fixed to the shaft S by a set screw 24. As illustrated toadvantage in Fig. 10, the sections of'the roller A are maintained inspaced relation by a ring 25, such rlng being of a. dlameterto fitwithin the area defined by the screws 23' so that no additional means isnecessary for securing the ring in proper position between the sections.

By this arrangement it will be seen that an annular slot is providedwithin the roller A and that the roller in the applied position as shownin Figs. 1, 2 and 3 receives the cutting edge of the blade B or B so asto allow the peripheries of the two rollers to contact with each other.The width of the slot in the roller A can be varied in accordance withthe thickness of the ring 25 so that blades of various widths may beused with the roller A at the same time securing the proper coactionbetween the two roller In operation, the sheets of paper'are fed betweenthe rollers R and the rollers A and A and during this operation theteeth of the blade B successively pierce the sheet of paper and therebyperforate the same. l hen the cutting blade B is employed it coacts withthe roller A in a manner identical to the blade B because of thecontinuous cutting edge a separating of the paper is secured.

Although I have herein shown and de scribed only one form of perforatingand cutting device embodying this invention, it is to be understood thatvarious changes and modifications may be made herein without and havingthe cutting edge thereof projecting beyond the periphery of thesections, means for securing the sections together, and a. second rollercomprising sections, fastening members extending through the sections atintervals and securing the sections together, and a ring interposedbetween the sections of the second roller and disposed within the areadefined by the fastening members for maintaining the sections in spacedrelation to accommodate the cutting edge of the blade.
